The getframe example doesn't work: impossible to convert stuct in double

Dear all,

I tried to run the simple example for making a movie usnig getframe. Unfortunately the example stops at the getframe line complaining that:

The following error occurred converting from struct to double: Error using double Conversion to double from struct is not possible.

Error in movietest (line 8) F(j) = getframe;

I remember with my prvious matlab version I had no problem. Someone can help me?

Thanks

Gabriele

This does not seem like a problem of the Matlab version, but concerns the type and size of F before the example runs. How did you initialize F? Perhaps all you need is a:

clear('F')

Well thanks,

at least it does something now...even though not good. This getframe function seems to me a bit failing.

Please explain any details. We cannot guess, what "seems a bit failing" means. Perhaps you omit the magic pause(0.02) after uicontrols have been created?
